Answer:
Explanation:
Mass of a proton, 
Mass of an electron, 
The distance between the electron and the proton is, 
We need to find the mutual attractive gravitational force between the electron and proton. The gravitational force is given by :
Where G is the universal Gravitational constant
So, the force between the electron and proton is 
.
Heat can travel as<em> radiation</em>, even if there are no particles of matter
along the way. Which is really lucky, because that's how we get
heat from the sun. And light too.
If you cannot get a chair to move across the floor, it is because static friction opposes your push. When you say static or kinetic friction the two object that facing each other are opposing each other. That's why you're having a hard time pushing the chair.
